    Campagnolo 8 speed dilemma

    I have an older bike that has Campagnolo 8 speed record (carbon) and my rear shifter isn't holding gear. I tried to have it fixed at the LBS, but they didn't get the job done. I suspect a cracked housing. I am not sure what to do with this? I already spent money trying to fix this once and now thinking about sending it all the way out to Seattle to Branford Bikes to see if they can fix it. I am a little concerned in doing so because I asked them if they could make sure it holds gear prior to sending it back to me and their response was a roundabout no. I asked, can't you just test to see if it holds gear? They seemed to not understand. I am a handy person, but no certified Camagnolo mechanic and even I know how to test if it holds gear. That is VERY easy to do. I don't really want to buy a whole new drivetrain and fall into this silly 11 speed stuff that makes no sense to me. 8 is more than enough and this did last a very long time.

    Anyone have any advice? I wish someone had an NOS shifter for sale somewhere, but I have had no luck in that either. Buying a used one may also be a dead end if it has the same issues.

    Thanks

    I don't know why the first shop couldn't fix it. Correct that, not all shops are familiar with ergo service, but they should know whether they can or can't. Ergo lever repair is unbelievably straightforward (I was Campy's east coast service tech for 5 years, until I quit) and your problem is almost certainly because of fatigued latching (G) springs, or a cracked support ring. These are inexpensive replacement parts and there's no adjustment.

    I can't understand why Branford is reticent about confirming that their repair will work because if you replace the broken parts it works, there's no halfway.

    Send it to Branford, or any qualified shop (I prefer the folks at Yellow Jersey in Madison) and there shouldn't be any problem except if there's more damage - like a cracked body.

    I have a suspicion there is a cracked body because the spring was supposedly changed. What can be done then? I believe Branford might have those parts. I will call Yellow Jersey on Monday as well. Maybe you have a NOS laying around.

    I've never heard of a cracked body.

    The G-spring carrier breaks (EC-RE011, discontinued and I have no idea if you can just cut the clock spring post off a newer one because the posts which fit in the shifter body are different looking) but they usually still hold gear after that happens (I've been riding a broken one for months).

    Take a look at the first generation manual http://www.campyonly.com/howto/ergotech.html, get a pair of EC-RE209 G-springs, buy a new Campagnolo inner cable (they usually have broken strands by the time you need new G-springs; and while Shimano cables are close the end is a little bigger and will get stuck), remember that the first generation right hand lever is held together by a left handed screw, and see what's going on in there. I've never bothered attaching the lever to a piece of handle bar when working on them as shown in the manual.

    You shouldn't have any problems as long as you have enough mechanical aptitude to adjust rear derailleurs (the hardest part) and tape handle bars.

    A cracked body would be visible under the hood, and not automatically cause weak latching. If you replaced the springs it's possible that the spring carrier is cracked. This is an inexpensive part and most of us who service Ergo replace it as well when replacing the springs, because it's better to do so than to look inept or redo the job if it cracks afterward.

    Everything on this shifter seems okay and the springs look new because they are black and show no wear. My shifter for the front derailleur sure sounds more stout than the shifter for my rear. I called Yellow Jersey and they said that part with the teeth inside is made of anodized steel and never wears out. I have to question that a little considering the difference in the two shifters. I suppose I could spread the tiny springs a little to add more friction, but don't want to mess things up.

    On another note, getting the tension spring that will keep pressure on the thumb lever is one heck of a tough thing to get in place. Does anyone know of any tricks to get that in place, or am I just muscling it in there. When I do that the spring is winding inward (compressing), correct? Hope I am going the correct way on that.

    Question one. Left shifter clicks are lighter than right ones on 8s shifters because the right detents on the cam are deeper, making a louder sound when the springs click home.

    There's sort of a trick to getting the thumb lever home against the spring, but it's mostly brute strength. Bring the lever as far high left on the lever body and slide it in using the corner of the body and levering the spring out of the way as you go. And yes, you want to be tightening the coil on the spring as you go in.
